Do you want baby ducklings next spring?
Do you want only eggs and don't want to deal with ducklings?
I'm guessing you aren't looking for a duck soup recipe?
Are you looking for fun pets that eat bugs in your grass?

They're going to be your babies, and at most you are only going to have these 4. Won't you be thrilled with whatever gender they turn out to be?

Well, then in my opinion (which should be taken with a grain of salt since I don't actually HAVE ducks) is that you'd want all boys... all the fun of a duck with no eggs. However, since you get to keep the eggs that hatch... I hope you get all 4!

Best of luck to you, honestly. Whatever is in those eggs is already adorable... and yours.
